k Problem 2 (30 pts) Blocks A and B are released from rest when the spring is unstretched. Block A has a mass my=3kg, and the linear spring has stiffness k=8N/m. If all sources of friction are negligible, determine the mass of block B such that it has a speed vp=1.5m/s after moving 1.2m downward, assuming that A never leaves the horizontal surface shown and the cord connecting A and B is inextensible. Use the work-energy principle. A B

Blocks A and B, with masses Ma= 5kg and Mb= 3kg, respectively, are connected by a spring of stiffness k= 20 N/m and unstretched length of 0.75m. The blocks are at rest and seperated by the distance 0.75m when block B is given a velocity to the rightwith magnitude v0=15m/s. The friction between blocks and the horizontal surface on which they rest is negligible. The picture given looks like: [A]---------[B] where the dashed line is the spring. Determing the maxium...

Block B of mass 10.0 kg is placed in contact with an unstretched spring on a horizontal, frictionless surface. The other end of the spring is attached to a fixed support. Block A with a mass of 4.00 kg is moving with a speed of 20.0 m/s when it collides with and sticks to B. (a) What is the speed of the combined blocks after the collision? The blocks compress the spring 2.60 m before coming to rest momentarily. (b)...

The spring provided in the
image has an unstretched length of 60 cm. If it is confined by a
small plate and awall, so that the length of confinement is 50 cm,
determine the initial speed of the 2 kg block in A. Assume that the
spring is farther compressed 5 cm when the block momentarily stops.
